STRAW-BURNER.

SPECIFICATION forming part of Letters Patent No. 482,862, dated September 20, 1892. Application filed March 31, 1892. Serial No. 427,246. (No model.)

To all whom it may concern:

Be it known that I, GUSTAV ADOLPH BYoR, a citizen of the United States, residing at Edgar, in the county of Clay and State of Nebraska, have invented a new and usefulStraw- Furner, of which the following is a specifica- This invention relates to trash burners or furnaces; and it consists in the construction and arrangement of the parts thereof, as will be more fully hereinafter described. and claimed.

The object of the invention is to provide a device of the character set forth which is convenient in its operation by virtue of the employment of independent burning-chambers, which may be filled with the trash to be burned away from the burner or furnace and replace a similar chamber which has become exhausted; further, to avoid smoke or smudging or dangerous consequences by causing the smoke to travel downward and then upward through a series of fines independent of the burningchamber.

In the drawings, Figure 1 is a perspective view of a straw or trash burning furnace embodying the invention. Fig. 2 is a similar view of one of the burning-chambers. (Shown removed.) Fig. 3 is a similar view of the parts of the furnace. (Shown separated and illustrat-ing the manner of joining the same.) Fig. 4 is a transverse vertical section on the line w a', Fig. 1. Fig. 5 is a transverse vertical section on the line y y, Fig. 2. Fig. 6 is a bottom plan view of one of the burning-chambers. Fig. 7 is a detail perspective view of the grate of one of the burning-chambers.

Similar numerals of reference indicate corresponding parts in the several views.

Referring to the drawings, the numeral 1 designates the base of the burner or furnace,

' which is of cylindrical form and has an opening- 2 in the top thereof and a flat rim 3 between said opening and the periphery of the same. The said base provides an ash pit or box and has a door 4 with a 51 e-damper 5 to regulate the draft, as will ,ifi understood. The said base is also provided with feet 6 and is surrounded by a foot-rail 7, projecting outward from the lower portion thereof. The rim 3 of the base has a number of collars 8, projecting upward therefrom and which surround openings extending through the said rim. The said collars are arranged in circular form, but do notextend wholly around the said rim, to thereby form an entrance to the opening 2 in the top of the base 1. On the said collars 8 are fitted flue-pipes 9, arranged in vertical position and having intersecting spaces between the same. For different purposes the number of these flue-pipes maybe varied, and their size may be increased or diminished, as desired. On the tops of the said pipes 9 is supported a dome 10, which forms a radiator and also has a primary function of receiving the smoke from the said pipes 9 collectively, and from the said dome the smoke passes out through a smoke-pipe 11, centrally located in the top of the said dome and provided with a damper 12, which is employed to regulate the draft in a manner well understood. The under side of this dome, as at 13, is formed or provided with a series of collars 14, in a manner similar to the rim 3 of the basel. The said collars l4 surround openings in the said lower side of the dome and are adapted to receive the upper ends of the flue-pipes 9. When the parts have thus been vconnected, they are firmly secured by tie-rods 15, extending upward from the bottom of the base 1 through several of the flue-pipes 9 and the top of the dome 10. To conveniently position these tie rods, they are inserted from the top of the dome 1O downward through the fluepipes and through the bottom of the base 1 and have removable nuts 16 on the ends thereof. The dome 10 over the opening 2 and outward through the entrance to said opening is obliquely concaved or arched, as at 16, to provide ready egress and ingress to the said opening, to thereby provide means for the ready insertion and withdrawal of burning-chambers 17.

The burning-chambers 17 are constructed cylindrical in form and form magazines for the reception of the trash to be burned. These chambers are preferably provided in duplicate, so that when one is mounted in position with burning material therein the other may be filled and made ready for the burning operation.

Each chamber is provided with a slidedamper 18 at the upper and lower portions of the front side thereof and a rotating damper 19 in the central part of the top of the same. The said dampers will be operated from time to time to regulate the draft 'of air to the burning mass within the chamber and are constructed in the simplest possible form. The lower portion of each of the chambers is formed with a rim or fiange20 a short distance above the bottom edge of the same, which is adapted to rest upon a rim 3, surrounding the opening 2 in the top of the base 1, and thereby providing a lower flange 21 below the said supporting-flange 20, which projects inward into the said base 1.

In order to readily remove the chambers, they are provided with handles 22 at the lower portion of opposite sides thereof and an up per handle or grip 23 for assisting in placing the chamber in proper upright position.

Within the chambers are secured a series of closed fiues 24, which extend from the bottom thereof to near the top of the same and are open at both ends. The said fines 24 are formed with a series of apertures 25 in their inner opposing sides, and also with slots 26 in the lower portions of the same about'in line with the rim or flange 20 on the outer surface of each of the said chambers. A perforate bottom or grate 27 is provided, having slots 28 extendinginward from the periphery thereof to fit ever the fines 24 in the chambers, said bottom or grate being provided, also, with a central handle or grip 29 for readily attaching or detaching the same.

.In line with the slots 28 and arranged radially are a series of slots 30, through which extend headed pins 31, connected to slidecatches 32 and projecting through said catches form heads for operating the same. When the grate is in position, the slide-catches are operated to engage the slots 26 in the fines 24, to thereby lock the said grate in position within the chamber.

The operation of the device is as follows: One of the chambers or magazines having been filled with trash is placed in position in the opening 2 of the base 1. The dampers having been suitably regulated, the trash is i gnited and the smoke therefrom, as well as par ticles of combustion, pass downward through the fines 24 by exiting through the openings or apertures 25 therein, and also through the tops thereof downward into the base 1. The said smoke and particles of combustion thence ascend through the fine-pipes 9 into the dome 10 and outward through the smoke-pipe 11. It will thus be seen that a greater radiatingsurface is provided in that the air may readily circulate between the flue-pipes 9 and become more rapidly heated; also, the dome 10 forms a radiator, and the base 1 as the heat becomes intense will in like manner increase the temperature of the lower strata of airsurrounding the same. While the burning .op-

eration is going on within the chamber or magazine in position, the ashes may readily drop from the same through thegrate 27 into the base 1, from whence they may be removed understood;

from time to time as it becomes necessary. One chamber having had its contents consumed it is replaced by another of similar construction which has been filled with a fresh supply of material.

The advantage of a construction as set forth resides in the convenient manipulation of the material to be burned without the resultant danger of feeding the material directly to a burning mass, and by the arrangement of the flues more heat can be obtained, as the exit of smoke and particles of combustion is tortuous and the effect will be readily It is preferable that the device be constructed of sheet metal to render it cheap in manufacture; but it will be understood that cast or other metal may be employed, if so desired.

Having thus described the invention, what is claimed as new is- 1. In a trash burner or furnace, the combination of a base having an opening in the top thereof, a series of fines extending upward fromsaid base, a dome supported by and connected with said fines, and a chamber or magazine removably fitted in the opening of said base, substantially as described.

2.
